Thanks for your reply. I'm aware only about one time when the bot was down and it voted after more than 9 hours. I had to change the hosting(I even tried postpromoter script) and I manually repaid 90% of the received funds.

I was unaware about other incidents, but to be frank I was not checking it very often. I will try to create a script to check all history to automatically repay the uncasted votes.

I perfectly understand your decision to unlist it. I will try to fix it and once done I'll contact you for a second chance. Hopefully I'll get it.
